What I Learned from Doing Research


I loved every bit of my 2+ years of research experience at Cornell. I was also grateful for the opportunity to participate in top conferences including WWW’21, CHI’20, and CHI’21. Overall, the experiences are life-changing, and I’d like to summarize some of my learnings here (constantly updating) as a reference to others and to myself.

Why Eigenvalues Are So Important


Okay, let’s bring out the question most professors would not bother to explain: why do we care so much about vectors that become a multiple of themselves when you multiply by a matrix?

Facts about Eigenvalues


First, some clarifications. We are considering linear maps from a finite-dimensional vector space to itself (also called an operator L(V)), as opposed to linear maps from one vector space to another vector space.
